I would probably have read all three books, since it says "trilogy" on my copy, but then I found out that he was writing more of them and decided I didn't like the books that much. Christopher Paolini pulled the same "trilogy" rug out from under my feet, but I kept reading those with feverish eagerness. (Yes, off-subject, but it had to be said.)
It's not a bad book, it definitely has some good points. It just really isn't one of my favorites.
